Everything You Need to Know About Your Roof’s Decking


Your roofing system is more than just the outer layer of shingles you see from the curb. Hidden underneath your shingles are layers of supporting structures that hold everything in place and contribute to the overall protection of your home.

One of the most important components of the roof is the deck. Winfield Builders, your local roofing company, discusses everything you need to know about it.

About the Roof Decking

The roof deck or sheathing is the layer of plywood that connects the roof to the frame of the house. It also acts as a foundation for the layers of underlayment and any type of roof covering such as asphalt shingles, metal panels or clay or concrete tiles. It plays an important role in protecting your home from the elements.

What Makes a Good Roof Decking?

An energy-efficient, well-built roofing system must have a solid decking that conforms to local building codes. To give the entire structure a secure foundation, it should be able to support the weight of every roofing material and accessory, hold constant loads like snow during winter, resist strong winds and impact loads, and anchor nails and other fasteners.

Roof Decking Options

Two of the most popular decking materials used in roof installations are plywood and oriented strand board (OSB). Plywood consists of thin layers of wood adhered together. Each wood layer features grains positioned at the right angles to ensure optimal strength and dimensional stability. 

OSB consists of cross-oriented thin layers of wood compressed and bonded together with waterproof binders. It is then formed into a wide mat before being installed over the roof’s frames.
